I have openclaw set up (and for the most part working well) on an Ubuntu VM running on my personal server. I have it set up with the Discord channel, so I can communicate with my agent via a discord DM. Occasionally, it will respond to a prompt, and then immediately respond again to the same thing. E.g. I will ask it to show me a file's contents, and it will do so, immediately followed by saying "I just showed you". At first, I thought this was just some weird behavior quirk, but I just looked at the chat log in the gateway dashboard, and I can see that the cause is that my messages to the discord bot are sometimes appearing duplicated. Is that a known issue?
